Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.
Transistor Fundamentals: Collector Saturation and Collector-Emitter Cutoff
Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.
In this animated learning object, learners examine how an ultrasonic flowmeter measures the flow of liquids through a pipe using ultrasonic sound waves. A short quiz completes the activity.
Learners listen to effective techniques to successfully interact with customers via the telephone. They also submit their own suggested replies to customers in various scenarios. Topics include general telephone etiquette, dealing with angry callers, working with confused or unsure customers, and managing voicemail. A quiz completes this customer service activity.
Concepts of Programming 9: Pseudocode Repetition Structures using While Statements
Explore repetition structures, which are commonly referred to as “Looping” statements, are a vital component of programming computer and industrial applications.
Nouns: Count and Noncount -- With the Articles "a" and "an"
In this interactive object, learners read how to use the indefinite articles "a" and "an" with singular count nouns. They omit these articles with noncount and plural nouns. The students then practice using "a" and "an" correctly.
Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.
In this animated object, learners examine automated manufacturing systems classified as motion control, batch process control, and continuous process control.
